The day I flew out of Terminal 5 bound for Paris is a day I would gladly forget. I was with Sara Fox, an American project director known as the "Queen of the Gherkin" for delivering that iconic building on time and on budget. The plan was that she would cast her forensic eye over every detail of the £4.3 billion Terminal 5 on behalf of the Evening Standard.

Today we publish reports of extraordinary scenes at Heathrow's Terminal 5, where some unfortunate passengers have been obliged to spend the night on the floor because of disruption caused by snow. Flights were cancelled because of the weather and reported shortages of de-icing equipment, passengers on incoming flights were unable to disembark because of frozen gantries, lifts were out of order and passengers were not told just what was going on - a failure which has characterised the chaos from the start. More flights are cancelled today.
